Three TTM successes in a row were from guys I had already gotten in the past. I think it just happened that way, but it doesn't happen often. I try not to send to the sake people over and over again, unless I have something really nice that I want to get signed. This 2013 Topps sapphire parallel of Adam Lind is the perfect example of a card I found and just had to get signed. The signature is hard to pick up in the scan, but it looks awesome in person.
I mailed to Lind on November 6 and got the card back on February 25, for a 101-day TAT.
